The dissociation of lime stone in the slag zone of the blast furnace is

Options

  1. Aexothermic accompanied by increase in cntropy
  2. Bendothermic accompanied by decrease in entropy
  3. Cendothermic accompanied by increase in entropy
  4. Dexothermic with no change in entropy

Correct answer

C. endothermic accompanied by increase in entropy

Step-by-step solution

Dissociation of lime stone is an endothermic reaction. Hence, entropy increases in this reaction.
